Fisher Exact Test help - (Mar/23/2011 )

Dear all

I am making a 2 x 4 contingency table, but one of the cells has an expected frequency of less than 5. Therefore I cannot use the chi-square to compare observed vs expected ratio, and will need the use the Fisher's Exact Test.

Most of the Fisher Test tutorials talk about 2 x 2 contingency tables, but I am not sure how to fit this into a 2 x 2 table...

Outcome 1 Expected: 6
Outcome 2 Expected: 4

Outcome 1 Observed: 0
Outcome 2 Observed: 10

Can someone let me know how to get around this?

Thanks so much all

Would it be:


out1 out2
expected 6 4 | 10
observed 0 10 | 10
--------------
6 14 20
